Their daughter, Mary, also became a painter and married Thomas, son of Robert Streeter, the Serjeant-Painter.
He and another Flemish painter George Geldorp who was like him a master in the Antwerp Guild of Saint Luke were very close associates of Anthony van Dyck in London.
Geldorp is believed to have been more involved on the commercial side by assisting van Dyck with the sale of copies of his works and frames.
[2] After the execution of Charles I of England in 1649, his art collection was broken up and sold off in order to repay the debtors of the former king.
[2] He was able to acquire the famous equestrian portrait by van Dyck of Charles I with M. de St Antoine.
He made a series of portraits of 14 "Beauties" after van Dyck, Lely and Samuel Cooper.
The series remained at Windsor Castle throughout the 18th Century and 13 of them reappeared in the Queen's Bedchamber in 1790 to 1819 and are now in the Royal Collection.
In 1667 Charles II commissioned van Leemput to make a small copy of the wall painting by Hans Holbein the Younger representing Henry VII, Elizabeth of York, Henry VIII and Jane Seymour at the Palace of Whitehall in London.
[2] Holbein's original draft cartoon for the left half of the composition is in the National Portrait Gallery, London.
